Application filed May 1, 1908. Serial No. 430,269.

To all whom it may concern:

Be it known that 1, AUGUST RosEN'rnAL, residing in Test Allis, in thecounty of Milwaukee and State of Wisconsin, have invented new and usefulImprovements in Discharge-Spouts for Corn Husking and ShreddingMachines, of which the following is a. description, reference being hadto the accompanying drawings, which are a part of this specification.

This invention has relation to improvements in discharge spouts forcorn-husking and shredding machines and relates more particularly tothat class of spouts in which pneumatic means is used for dischargingthe material therethrough.

The principal object of the invention is to provide a discharge spoutwhich may be turned or bent to any convenient angle or height todischarge material from the husker.

A further object of the invention is to provide a discharge spout whichis adjustable as to length. And a still further object of the inventionis to provide a discharge spout which is simple in construction andinexpensive to manufacture andwhich contains but a minimum number ofparts.

With the above, and other objects, in view, the invention consists ofthe devices and parts, or their equivalents, as hereinafter set forth.

In the accompanying drawings, in which the same reference charactersdesignate the same parts in all the views; Figure 1 is a side view ofthe discharge spout of a cornhusking and shredding machine embodying myimprovements, a part being broken away to show details of construction,and the nor mal position of the discharge end of the spout being shownin dotted lines; Fig. 2 is an end view of the spout; Fig. 3 is avertical sectional view of a portion of the flexible elbow of the spout;Fig. 4 is a transverse sectional view taken on line 4-4 of Fig. 1; Fig.is a transverse sectional View taken on line 5 5 of Fig. 1; and Fig. 6is a modified form of the flexible elbow construction.

Referring to the drawings, the numeral 8 indicates a fan casing of acorn-husking machine, and 9 the fan contained therein. This fan and itscasing are of ordinary construction, the casing being provided with aninlet opening in its side and with a tubular vertical discharge pipe 10connected to its periphery and is adapted to receive material from thehusking machine through its side opening and to discharge the samethrough the vertical discharge pipe. A cast metal ring 11 provided witheyed cars 12' is revolubly mounted on the top of discharge pipe 10 andis adapted to have connected thereto by means of bolts 13 passingthrough the ears thereof a similar ring 14, these rings serving as ahinge connection by removing one of the bolts and using the other as thehinge pin. The discharge spout consists of a flexible elbow 15, astraight section 16, an extensible; section 17 and a flexible dischargeend 18 connected together and fastened to the ring 1 1 by rivets orother securing means.

The flexible elbow is formed of a strip of sheet metal 19 wound spirallywith one of the side edges thereof overlapping the edge of the adjacentconvolution thus forming a flexible tubular elbow. The portions of theconvolutions of sheet metal formin the outer curve of the elbow arespaced apart and connected to a flat spacing spring 20 bolted to eachconvolution by bolts 21. and the portions of the convolutions formingthe inner curve of the elbow are riveted to a flexible strap or chain 22by rivets 23 so as to permit a limited extension of one convolutionwithin the adjacent convolution. The flexible strap is of such lengthbetween the rivets as to prevent the entire withdrawal of oneconvolution from another when the elbow is straightened out. The inneredge of the sheet metal is of less diameter than the outer edge in orderto keep the elbow of the same diameter throughout its length as shown inFig. 3. It will be noticed that the overlapping of the convolutionsextends in the direction of the movement of the discharging material inorder to avoid the abrupt shoulders formed by the joints of theconvolutions. The straight section 16 is connected to the elbow byrivets and may be of any convenient length, and the extensible section17 is connected to a ring 16 revolubly mounted on the outer end of thestraight section of the spout. The extensible section is similar inconstruction to the elbow, being formed of a strip of sheet metal 24wound spirally to form a tube with the top and bottom portions of eachconvolution being connected to adjacent convolutions by means of a chainor flexible strap 25 and eyed pins or staples 26, the chain being ofsuch length as to prevent the separation of one convolution from anotherwhen the spout is extended full length. The flexible discharge end 18 ofthe spout is identical in construction with the elbow,being formed of astrip of sheet metal 27 Wound spirally and connected to a spacing spring28 by bolts 29, and provided with a flexible strap 30 riveted to eachconvolution of the spiral. The spacing spring 28 is of sutl'icientstrength to normally lift and hold the discharge end or" the spout inthe position shown in dotted lines in Fig. 1 and in order to bend theend downwardly at any angle desired a rope or cable 31 is connected tothe discharge end of the spent and by means of which the angle of theflexible discharge end may be adjusted. 7

Each COHYOllItlOl'l ot' the extensible section of the spout is providedwith two guide straps 82. positioned one on each side, and bars 33extending parallel with the straight section are disposed in the eyesformed by the straps and the sides of the extensible sections and serveas the means for expanding and contracting the extensible section andalso as a support :l or each convolution thereof. The outer ends ofthese bars are bolted to the sides or the outer end convolution of theextensible section and the inner ends of the bars are bolted to anadjusting ring surroundingthe straight portion of the spout. A slidingring 35 provided with eyes 36 also surrounds the extensible section ofthe spout near its outer end and the inner ends of the chains 25 areconnected to the eyes 36. The medial portions of the bars are bolted tothis ring and are adapted to slide the said ring back and forth inadjusting the extensible section on the straight section of the spout,the ring serving as a brace or support for the bars. The upper portionof the adjusting ring 34: is of greater diameter than the straightsection of the spout to provide space between the ring and the spout torthe bars and the outer end of a lever 37 which is bolted fast to thestraight section of the spout and extends inwardly, or to the leftlooking at Figv l, to a position above the elbow and the fan. This leveris pivotally supported between the upper ends of two supporting members38 which are pivotally bolted to the sides of the ring l-'l-. The leveris strengthened by means of a tie rod 39 connected to both ends ot thelever and passing over a block positioned above the pivotal connectionof the lever.

A threaded adjusting rod 40 is pivotally connected to the ring 14 andextends upwardly at an angle and passes through an opening in the end ofthe lever and is provided with a cranked nut 41 which is adapted toraise or lower the outer end of the l spout by turning the nut up ordown on the threaded rod and changing the angle of the tlexible elbow.

The forward end of the lever is provided with a series of verticalapertures 42 which are adapted to receive a locking pin 43 passingthrough one of the openings 4% in the sliding ring 34 to adjust thelength of the extensible section of the spout. The openings sla in theenlarged portion of the ring are adapted to serve as adjusting means for"turning the extensible section and the tlexible discharge end 01 thespout on the straight section to provide for a lateral discharge.

ln the principal form of the invention the sheet metal strip forming theelbow is tapered or reduced in diameter at its inner edge by cutting theblank to shape to produce this result, whereas in the modified form ofconstruction shown in Fig. (3 the same result is obtained by cuttingeach convolution part way and drawing the cut riveting them together.

From the above description it will be seen that a discharge spout isformed in which all positions of adjustment are provided tor in a verysimple manner. By means of the flexible. elbow, the threaded rod, thelever. and the cranked nut, the spout may be tilted to any angle desiredto raise or lower the discharge end of the spout. If it is desired tolengthen or shorten the spout the locking pin is removed and the slidingring is moved back and forth. as the case may be, causing the spirallyformed extensible section to slide on the straight section of the spout,and when the proper adjustment is obtained the locking pin is insertedthrough one of the the apertures ot the lever.

of the spout the locking pin is removed and ot the extensible sectionand the discharge end of the spout, and when the desired angle isreached the pin is replaced in the aperture of the lever and through theopening in the sliding ring in register therewith. The angle of thedischarge end ot the spout may be adjusted by pulling on the rope anddrawing the end downwardly against the upward tendency of the spacingspring. The whole spout may be revolved by means of the swiveled jointbetween the spout and the fan casing. It is obvious that this spout maybe used with other machines than corn huskers and it is to be understoodthat the invention contemplates the use of the spout with all kinds ofmachines in which material is discharged and elevated.
